For a long time, the earth was thought to be the center of the universe. However, this theory was put to rest when a model of the world was made in which the sun, not the earth was at the center of the universe. The Heliocentrism theory was contradictory to geocentrism which placed the earth at the center of the universe. The first model was presented by Renaissance mathematician Nicolaus Copernicus and perfected by Joseph Kepler to include orbits in the 16th century. When Galileo Galilei used the telescope to observe the universe, he supported the observations. This was the first step into man’s curiosity about what was beyond the earth.
